It is not always easy for the public to see ______ use a new invention can be of to human life.
A whose B.what C which D.that

It is not always easy for the public to see ______ use a new invention can be of to human life.A whose B.what C which D.that
答案是B
公众对于一项新的发明在人类生活中有“什么”用处并不总能轻松地看出来.
see后面接的肯定是一个宾语从句了,从句缺少一个代词“什么”,that和whose都不能选,因为它们在名词性从句中不能作代词,重点在于what 和 which 选择哪一个,有两种解释~
1.面对高考,只要是名词性从句,缺少成分,优先选择what,正确的几率并非99%,是100%
2.真的要解释的话,what没有范围,而which是在限定范围去选择,比如:茶和咖啡,你喜欢哪一个,这时用which,而本题并没有限定用处的范围,所以用what
希望对你有帮助,我认为我讲的已经比较清楚了,不懂再问吧~!若有可能,求追加悬赏

C.

选C

选D 首先判断出can是谓语,前面 必须是主语,排除that(不能做主语)和how(后面要加to)这里面如果用which是因为有”use a new invention“这样的动词
